अन्नावरील प्रारणांच्या प्रक्रियेबाबत खालीलपैकी कोणती विधाने बरोबर आहेत ?
(a) याचा वापर साठवण कालमर्यादा वाढविण्यासाठी आणि निर्जंतुकीकरणासाठी करतात.
(b) या प्रक्रियेत गॅमा किरणे व अवरक्त किरणे यांसारख्या उच्च उर्जायुक्त प्रारणांचा उपयोग होतो.
(c) हि प्रक्रिया बटाटे व कांदे यांना अंकुर (फोंब) फुटण्याची क्षमता क्षीण करते.
(d) या प्रक्रियेत वापरल्या जाणाऱ्या प्रारणाची मात्रा 'गॉस' या एककात व्यक्त करतात.
पर्यायी उत्तरे :

The correct answer is Option A (Only (a) and (c)).

Key Points:
• Food Irradiation Technology: Food irradiation is a cold process of exposing food to ionizing radiation:
• Shelf-life Extension & Disinfestation: Statement (a) is correct; it controls spoilage organisms, eliminates foodborne pathogens, and disinfests grain pests without chemical residues.
• Sprout Inhibition: Statement (c) is correct; low-dose irradiation (0.06 - 0.15 kGy) inhibits cell division in tuber eyes, preventing potatoes and onions from sprouting in storage.
• Radiation Types: Statement (b) is incorrect; only ionizing radiation (Cobalt-60 gamma rays, electron beams, and X-rays) is used; non-ionizing infrared rays are never food irradiation sources.
• Radiation Dose Units: Statement (d) is incorrect; radiation absorbed dose is measured in Gray (Gy) or kiloGray (kGy) (1 Gy = 1 J/kg), whereas Gauss is a unit of magnetic flux density.
• Official Key: Only (a) and (c) are correct, confirming Option (1).
• Key Takeaway: Food irradiation uses ionizing gamma/X-rays (measured in Gray) to extend shelf life and inhibit sprouting in onions and potatoes.
